Subsequently, the bubble generation supply unit 400 supplies a part of the contaminated water to the pressurizing pump 410, and the air supplied from the compressor 420 is sent to the micro bubble generator 430 so that the solubility of air in the water is saturated Resulting in early microbubble generation.

In this process, natural or artificial coagulant is supplied through the coagulant feeder 450 to add the coagulation function, thereby enhancing the removal efficiency of the contaminant.

The micro bubble generator 440 discharges the micro bubble generation water supplied from the micro bubble generator 430 through the micro bubble supply hole 441 and generates micro bubbles by the pressure difference at the time of discharge do. The microbubbles released in the water improve the growth and ecological environment of fishes and microorganisms by increasing the dissolved oxygen concentration and adhere and float the particulate pollutants to the microbubbles, And then the removed contaminants are removed through the biological oxidative decomposition process by the microorganisms inhabiting the water unit 600 and the filtration unit 200, The circulating water pumped by the filter unit 200 is dumped into the vegetation unit 500 and the filtration unit 200 and is removed by filtration, adsorption, and oxidative decomposition by microorganisms. The microbubbles also purify the water quality by oxidative decomposition of the dissolved organic matter due to the oxidizing power generated when the bubble breaks.

Here, the micro bubble diffusing means 440 is vertically movable according to the water depth by the driving means (not shown), and the discharge position of the micro bubble can be adjusted according to the water pollution state according to the water depth.

Subsequently, the vegetation unit 500 can naturally purify contaminants by absorbing organic matter and nutrients such as nitrogen and phosphorus in the water for the growth of the plant itself and the growth of microorganisms in the root of the plant. The pollutant that has not been treated in the vegetation unit 500 passes through the filtration unit 200 and performs filtration, adsorption, and catalytic oxidation decomposition by microorganisms to purify the water quality.

In addition, the photo-oxide adsorption unit 700 is for increasing the efficiency of water purification using natural sunlight. As described above, for example, titanium dioxide (TiO ₂ ), zeolite or the like is coated on the surface of a foamed foamed styrofoam The mixed coatings improve the water quality by the photo-chemical decomposition of dissolved organic matter in water by TiO ₂ by photochemical action and the adsorption action of phosphorus by zeolite.

On the other hand, the water quality monitoring unit utilizes on-line sensors of the multi-item water quality measuring unit to measure water temperature, pH, dissolved oxygen (DO), turbidity, organic matter (BOD, COD, TOC), nutrients Nitrogen) or chlorophyll-a, and the measured data is analyzed by the water quality analysis unit. In addition, the control unit judges whether the measured water quality satisfies the target water quality based on the operation of the contaminated water bodies such as rivers, lakes, reservoirs, and sea areas for a target driving cycle set in advance, If the target water quality can not be satisfied for each pollutant item, the target water quality is achieved by operating each unit in a stepwise manner.

As described above, the fused composite part type water quality purification system and the method of operating the same according to the present invention can improve the quality of water directly and improve water quality by employing a complex purification and filtration technology for water bodies such as polluted rivers, lakes, reservoirs, There is an advantage that more efficient water quality management can be carried out through prevention of pollution.
